 **This sprint**
 
 Objective 1, KR 1: Enable Developers and the Flow Foundation to simulate Cadence 1.0 Contract upgrades
 * [Emulator release is ready](https://github.com/onflow/flow-cli/releases/tag/v1.17.0-cadence-v1.0.0-preview.19), support devs that are teting migration, monitor Discord questions.
 
 Objective 1, KR4: Testnet Upgrade to Crescendo Release
-* Testnet migration completed, moving on to adding [Atree register inlining](https://github.com/onflow/cadence/pull/3048) migration and validating migrated state on the TN migration environment.
+* Completed Testnet migration with both Atree inlining and Cadence 1.0.
 * Continue work on migration optimizations.
 * Continue with [EVM Gateway development](https://github.com/onflow/flow-evm-gateway/issues/126) and [EVM Core development](https://github.com/onflow/flow-go/issues/5536) for production readiness.
